Hi All, Thanks all information. I am a little bit confused about LLQ. Below is my understanding after digesting some documentation and feedback from others. Please correct me if I'm wrong. 1. LLQ=PQ+CBWFQ and PQ is defined by using 'priority' 2. if using 'bandwidth', then I'm not using LLQ. What

Hi, I have 2 routers configured with HSRP and running BGP with single ISP. For outbound traffic, it will go through the Active HSRP router. How about Inbound traffic? Can the Inbound traffic be 'load shared'? (The ISP already make the same preference on our route advertised) Or the Inbound

Hi All, Thanks all your response. Now two routers adverise same block /24 to the isp. I found that they are 'load shared' in this sense. Only 1 link is the active for Inbound. For example, if I download files from outside, inbound is using say link1 and link2 is idle and no packet coming in.
